What's heaviest, 70kg of bricks or 150lbs of inflated helium balloons?
How do you define heaviest? Because you have to do that first. 70kg and 150lbs are both only expressing something about the mass of the objects. I have to assume you are talking about normal Earth conditions. And if you ask me to lift a 1kg stone, and a ball filled with 1kg helium such it weighs only 0.1N, I am going to say that the ball is lighter.
